Question

我对python很陌生，但我会尽力解释。我有一个类似1234567890的输入，我希望它在数字较大时更具可读性，并且希望像这样的格式1,234,567,890。

from datetime import datetime
    def price_calc():

    the_item = 38
    amount_of_the_item = input("Amount of items: ") #This output is what i want to change.

    price = ((int(amount_of_the_item)) * (int(the_item)))

    print("{:,}".format(price),"USD")

    now = datetime.now()
    t = now.strftime("%H:%M:%S")
    print("Time", t)

while True:
    price_calc()

现在我可以从控制台获得此信息：

Amount of items: 1234567890
46,913,579,820 USD
Time 01:22:29

但是我想得到这个：

Amount of items: 1,234,567,890
46,913,579,820 USD
Time 01:22:29

控制台输出的第一行是我要更改的内容。

我以某种方式解决了问题，使用户的输入在显示在屏幕上之前就已经从终端清除了，我仍然有值

旧代码

from datetime import datetime

def price_calc():

    the_item = 38
    amount_of_the_item = input("Amount of items: ") #This output is what i want to change.

    price = ((int(amount_of_the_item)) * (int(the_item)))

    print("{:,}".format(price),"USD")

    now = datetime.now()
    t = now.strftime("%H:%M:%S")
    print("Time", t)

while True:
    price_calc()

新代码

import os #NEW
from datetime import datetime


def price_calc():
    os.system("cls") #NEW
    the_item = 38
    amount_of_the_item = input("Amount of items: ")
    print('\033[1A[\033[2K\033[1G', end='') #NEW
    print('Amount of items: {:,}'.format(int(amount_of_the_item))) #NEW

    price = ((int(amount_of_the_item)) * (int(the_item)))

    print("{:,}".format(price),"USD")

    now = datetime.now()
    t = now.strftime("%H:%M:%S")
    print("Time", t)

    input("Press Enter To Continue") #NEW. This is a buffer so the code dont clear it self before i can read it.

while True:
    price_calc()

我现在得到的控制台输出是：

Amount of items: 1,234,567,890 46,913,579,820 USD Time 15:15:59 Press Enter To Continue

感谢您提供的所有帮助。

有没有办法在python中更改用户的输入？
